PATENT CHECK-ROW DROPPER.

SPECIFICATION forming part of Letters Patent No. 290,950, dated Decombzr25, 1883,

Application filed August 2 1883.

To all whom it may concern.-

Be it known that I, J OHN HOWARD WAR- nEN, a citizen of the UnitedStates, residing at Burlington Junction, in the county of Nod away andState of Missouri, have invented a new and useful Cheek-Row Dropper, ofwhich the following is a specification.

My invention relates to improvements in check-row corn-planters; and itconsists in the construction, combination, and arrangement of theseveral parts, as will be hereinafter described.

In the drawing I have shown in pcrspee tive the main frame andcheck-rowing devices of a corn-planter constructed according to myinvention. The bars a a and a constitute the main frame: The bar a issupported on the forward ends of and at right angles to the bars a, anda bar, a", is secured to and connects the rear end of the said bars, asshown.=: Brackets b b are projected forward from the bar a and providebearings for the shaft Z as well as a means for preventing longitudinalmovement of the roller A along the said shaft. This roller, it will beseen, is fixed on the shaft .bbetween the brackets b, and is providedvided with a pin or stud, H,'which projects into the cam-slots A. As theroller is revolved, it will be seen the pin H, traversing the cam-slot,will give the lever C a rocking motion on its pivot, which, beingeommuni cated to the dropping-slide, gives the latter the reciprocatingmotion desirable in machines of the class to which my invention is mostuniversally adapted.

On the onterends of the bar a, and at right angles thereto, I securebarsa", through which the shaft 1) extends, and in which it hassupporting-bearings. On the ends of this shaft I secure grooved pulleysB, having forks B, which are engaged by the knots of the wire in theoperation of the machine. Brackets G are mounted on the bar a" onopposite sides of the pulley, and provide bearings for the guide-pulleysg 9, one arranged above the other, as shown. The npperpulley, g, is ad(No model.)

justable vertically by means of slot in the brackets and set-screw onthe pulleys spindle for the purpose of varying the depth ofthe wire inthe main pulleys B A guidebar, D, is pivoted centrally on the bar a andis provided on its outer end with guidepulleys E E. A tension-arm, D,projects rearwardly from the bar D at the center thereof, and its outerend rests between two pins, F, mounted on plate F, secured to the bar aThis arm D has aslight play between the pins F, and is preferably madeof spring material, so as to permit a greater oscillation or vibrationof the bar D in the operation of the device.

It will be understood that the wire is placed on themachinc in thefollowing manner, to wit: around one of pulleys E, thence across themachine parallel to bar D and around the other pulley-E, and forwardbetween pulleys g g and over pulley B, operating the latter by means ofthe knots engaging the forks.

The bar D, it will be seen, serves the part of a guide for the rope, andbeing pivoted and provided with tension-arm D, is capa-V ble of a slightpivotal or vibration motion, as is desirable in check-rowing machines,from the uneven feeding along the wire, result ing from roughness orunevenness in the ground. l

I am aware that prior to my invention check-rowers have been in use.Therefore I do not claim such a combination, broadly; but

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is-

1. The combination, with the frame having pins F, and the forked pulleysB, arranged 011 opposite sides of the frame, of the oseillatingguide-bar D, pivoted midway its ends, the tension-arm D, fixed at themiddle of the guide-bar and projected between the pins F, andguide-pulleys E, fixed on the ends of the bar D and in position toreceive the cord in the passage of same tothe forked pulleys,substantially as set forth.

2. The combination, in a corn-planter, of the framing, the shaftjournaled therein and provided with roller A, having cam-slot, the lever0, having pin H fitted into said groove, the forked pulleys secured onthe ends of the IOC shaft, the guide-pulleys G G, arranged on oppositesides of and below the plane of the upper side of the forked pulleys,the bar F, the pins F, mounted on said bar, and the pivoted guide-bar1), having pulleys E E, and provided with the spring-arm D, extendedbetween the pins F, all arranged and operating substantially asdescribed and shown, and for the purposes set forth.
